Patent GB-1042863-A (GB)
Title: Process for obtaining a thermoplastic substance capable of expanding to cellular form on heating
IPC: C08J9/18
Filed: 1963-04-29
Abstract: Synthetic thermoplastic substances are made to be heat-expandable into a cellular structure by incorporating a suitable gaseous or liquid-expanding agent into the substance while in a non-cellular, particulate form maintained in a stabilized aqueous suspension by a suspension stabilizer at superatmospheric pressure and at a temperature above its softening point.  Preferred thermoplastic materials are beads of polystyrene, polyvinyl chloride, and polymers and copolymers of acrylic acid esters.  The suspension may be obtained by using directly the products of an aqueous suspension polymerization process, or else by suspending suitable beads or ground particles in an aqueous system.  The suspension is stabilized in all cases by a combination of a water-soluble organic suspending agent and an ionic organic wetting agent.  For suspensions that are the end product of an aqueous suspension polymerization process, the stabilizing system used is partially hydrolysed polyvinyl acetate (80-90% hydrolized) and polymethyl methacrylate (25% hydrolysed), but for other suspensions, various mixed agents are employed. Preferably a strongly dissociated alkali or alkaline earth metal inorganic salt (e.g. NaCl, Na2SO4 or CaCl2) is also present.  Expanding agents are suitable liquids that are compatible with, but not solvents for, the thermoplastics, and have a boiling-point lower than the softening temperature of the thermoplastic material (e.g. aliphatic hydrocarbons), or are gases, either inorganic, or organic, for example nitrogen or hydrogen, or low molecular weight aliphatic gases.  Incorporation of the expanding agent is preferably performed in the presence of small quantities of water-insoluble organic liquids that are solvents for the thermoplastic particles, such as aliphatic halides or aromatic hydrocarbons. The process may be performed in an autoclave at temperatures of up to 50 DEG  C. in excess of the softening point of the thermoplastic, the incorporation of expanding agent taking up to five hours.  Many worked examples are given for making expansible polystyrene and polyvinyl chloride beads. The uses of the invention derive from its being economical in cost and time, and productive of a stable material of good storage properties capable of giving expanded products of low density and shrinkage.

Title: Method of pre-carburization of drill steel
IPC: C23C8/00
Filed: 1963-04-30
Abstract: A process for producing a hardened hollow steel member, e.g hollow drill steel, bearing races &c., comprises hardening one of the surfaces of a hollow steel billet of at least 4 inches thickness having a hole therein of at least 1 inch diameter, the hardening being effected at an elevated temperature, e.g. 1750-2300  DEG F. in the presence of carbon or other diffusion hardening element until a hardened layer is formed and subjecting said member to mechanical deformation, e.g. rolling under pressure at a suitable high temperature to effect considerable reduction in cross-sectional area such as to produce a desired shape of hollow steel member, thereby refining the grain structure and improving the physical properties of the hardened surface layer and further carburizing said surface to deepen said layer within said surface and to produce at least one further hardened layer.  After the first case hardening and mechanical deformation the member is subjected to a high temperature diffusion treatment at 1600-1900  DEG F. for 2-6 hours for the purpose of deepening the hard case further into the metal.  The second carburization is effected in a lower temperature range of 1650-1750  DEG F. in order to limit the grain growth. Finally, in order to restore the carbon case at both ends, a gas carburization takes place, at the lower range of temperatures of 1600-1700  DEG F. for 6-8 hours followed by oil quenching and annealing at 450  DEG F. for one hour.

Abstract: 746,021. Agglutinated fibrous sheet materials; laminated sheet materials. OWENS - CORNING FIBERGLAS CORPORATION. July 24, 1951, No. 17561/51. Class 140. [Also in Group IX] A web of blast - attenuated mineral fibres such as glass is reinforced by one or more continuous glass fibre strands. The reinforcing strands may be doubled back and forth in irregular loops and coils, may be in parallel spaced arrangement, may be in regular sinuous arrangement, or a combination of these methods may be employed. A binding agent may be incorporated, e.g. by spraying. As shown, one or more strands 35, Fig. 1, are fed from bobbins 26 by compressed air feeding-nozzles 25 into a chamber 14 in which fine glass fibres are formed by the action of gaseous blasts from a blower 12 upon streams of molten glass from a feeder 10. The strands 35 fold back and forth in loops and coils as they fall among the descending glass fibres. The reinforced web is collected on a perforated conveyer 15 moving over a suction box 20. An adhesive may be sprayed on the web at 42 and further adhesive may be applied by passage of the web through a trough 47. The adhesive is dried or cured in an oven 50 through which heated air circulates. The air may be partly preheated by drawing it through the web at 57. The adhesive may be a gum, asphalt, coal tar, pitch, phenol - formaldehyde resin, rubber, starch, sugar, gelatin, polystyrene, or polymethyl methacrylate. Alternatively, glass fibres attenuated from one or more nozzles 100<SP>1</SP>, Fig. 12, fall through two or more chambers 109<SP>1</SP> for collection in superposed layers on a perforated conveyer belt 31<SP>11</SP>, the reinforcing strands being laid on a deposited layer of fibres by stationary or transversely reciprocating feeding devices 120<SP>1</SP> and covered by the next layer. Strands may be fed into one or more of the chambers 109<SP>1</SP> to fall in coils and loops, and adhesive may be sprayed into the chambers at 150.
